As a former competitive swimmer who has had to re-learn how to swim for tri I second the advice on rotation.

You shouldn't have to move your head much if you are rotating effectively through the hips with a strong core. Also make sure you are breathing out between breaths, it makes the inhalation much more instinctive.

Can a "convertible" wetsuit be developed. Similar to the concept of cycling leg and arm warmers but manufactured so that they are streamlined. Allowing a cold water suit to be used in other conditions.
